CHARLES B. POST, OF NEW LONDON, OHIO.

DETACHABLE HANDLE.

To all whom it may concern:

Be it known that I, CHARLES B. Pos'r, a citizen of the United States, and resident of New London, county of Huron, State of Ohio, have invented certain new and useful lImprovements in Detachable Handles, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The objects of the invention are to pro-. vide means for detachably securing together a sleeve or socket portion and a central stem or rod closely fitting therein, and to so attach the parts together as to prevent rotation of one part on the other and I exemplify the invention in its adaption for use in securing a handle to an umbrella stem in which use it has many advantages. The objects to be obtained in this use may be enumerated as follows: It permits of interchangeability of several styles of handles, and the removal of the handle if expensive when the frame and cover of the umbrella are worn out, since an ornamental and costly handle will wear longer than several covers and frames and in this manner can be saved for future use. It is also useful in permitting separation of the handle from the frame to engrave the handle.

Further advantages are found in the compactness of the article when removed for shipping` or packing in trunks or suit cases and also the handle can be removed to prevent theft of the umbrella, since without an ornamental handle the umbrella would lose much of its attractiveness.

Further objects of the device are to provide a shank or sleeve adaptable to all kinds of handles which is simple in construction, so as to be easily operated by any one without danger of making mistakes or of injury to the umbrella, will preserve the full strength of the stern at the point of greatest strain, can be attached and detached without removing the cover from the umbrella, can be easily operated with gloves on. Also the mode of operation is simple and there are no objectionable projecting parts or hooks when the parts are separated.

The device is also durable, neat in appearance, and of slight initial cost, and has elements of increased efiiciency and practicability in whatever uses it may be emplyed he invention consists primarily in outer Specification of Letters Patent.

and inner telescoping portions and the spring catch or detent formed integrally in the outer portion or sleeve and a shoulder in the inner portion or stem, with added means for releasing the catch readily accessible from the exterior of the outer sleeve.

rIhe device by means of which the union is made comprises a socket piece adapted for insertion in the umbrella handle. The outer end of the socket piece forms a sleeve which fits closely over the tubular stem of the un'ibrella.

To prevent detachment of the parts a shoulder is formed in the side of the stem near its inner end, and a spring detent or catch is formed integrally from the wall of the sleeve and engages with this shoulder. 'Io release the spring from the spring catch a flattened pin is inserted in the spring catch and passes through the walls of the stem and sleeve and is terminated by a button or expanded part adapted to be easily pressed by the finger while grasping the handle.

To permit of separating the parts, the pressure pin passes through open slots in the end of the stem, and the pin is made broad enough to find a firm bearing in the slot, so as to prevent rotation and rattling of the parts.

The invention as illustrated in the accompanying drawings, is hereinafter described, and specifically pointed out in the claims.

In the accompanying drawings, Figure l is a longitudinal sectional view of the device; Fig. 2 is a face View of the inner end of the stem showing the slotted extremity thereof and the shoulder, on each side of the slot; Fig. 3 is a similar view of the socket, showing the depressible button and the slot through which it passes; F ig. Jf is a view of the opposite side thereof showing the spring detent formed integrally out of the wall of the sleeve and Fig. 5 is a side view of the extremity of the stem showing the shoulder cut from one side thereof through its wall. Fig. G is a vertical section showing a modified form; and Fig. (3n is a detail of modified pin.

In these views 1 is the umbrella stem, 2 the handle, which may be of any desired character, 3 is the socket piece which is provided with a shank portion, preferably of the size of the stem where it enters the handle, and its outer end f1 is of requisite size to form a sleeve fitting closely over the extremity of the stem. The wall of this sleeve is slotted longitudinally in parallel lines at 4J, and transversely at 5, to form a tongue T which is separated therefrom on three sides but integral therewith at one end and is bent inwards at its tip 5. The sleeve being made of tempered metal a spring detent is formed in this manner which is adapted to engage the shoulder 6 cut in the wall of the stem, as soon as the stem is inserted in the sleeve socket 3.

rEhe inner end of the stem abuts against the inner annular shoulder 7 in the sleeve at the moment that the spring catch engages the shoulder 6 in the stem, so that the parts are rigidly locked together.

To depress the spring for the purpose of releasing the stem, a pin S is employed. This pin extends through the open longitudinal slots 9 in the extremity of the stem and through a shorter slot l0 in the wall of the sleeve and projects beyond the sleeve so that its head il can readily be pressed by the linger. rllhe open slots 9 permit the pin to pass out of the stem when the spring is released and the pin is broadened to form a firm hearing surface and to prevent rotating` the parts on each other.

in use the handle can be grasped in one hand and the stem in the other. The spring can then be depressed easily to detach the parts so that the handle and sleeve can be pulled away from the stem.

(j shows a sectional vview of a modilied forni of pin and Fig. 6"l is a detail of the same.

Having described the invention what l e .im as new and desire to secure by Letters Patent is l. ln combination, with a socket piece, Comprising, shank and sleeve portions, a stem adapted for insertion in said sleeve, a spring detent cut integrally from the wall of the sleeve and turned inwardly at its tip, a shoulder in the stem which said spring detent adapted to engage when the parts are brought together and means for releasing said spring accessible from the exterior surface of said sleeve, said releasing means forming also means to prevent the rotation of one part on the other.

2. The combination with a socket piece, comprising, shank and sleeve portions, of a stem insertible in said sleeve, a shoulder in said stem, and a -spring portion formed integrally in the wall of the sleeve, said spring forming a detent operatively connected therewith and adapted to engage with said shoulder in said stem when the parts are brought together, and a pin adapted to pass through the walls of said sleeve and stem and attached to said spring, said stem being longitudinally slotted at its extremity in both sides to permit of the free movement of said pin when the parts are separated.

3. The combination with a socket piece, comprising, shank and sleeve portions, of a stem insertible in said sleeve portion a shoulder on said stem, a tongue forming a spring detent, operatively connected with the wall of said sleeve, said sleeve provided with longitudinal and transverse incisions adapted to separate said tongue therefrom on sides and end, said tongue adapted to engage said shoulder when the parts are assembled, a shoulder in the sleeve against which said stem abuts, a depressible pin extending through the walls of said sleeve and stem and connected with said spring tongue, the walls of said stem being longitudinally slotted to permit the withdrawal thereof when the spring is released.

e. The combination with a stem and sleeve thereon, of an integral spring detent in said sleeve, adapted to make engagement with said stem, and an operating pin'for said spring said pin adapted to prevent rotation of said parts upon each other.

rlhe combination with telescoping sections, of a spring detent out of contact with the body of the outer section on three sides and integrally attached thereto, a shoulder' in the inner section adapted to normally engage said spring detent, and a releasing means for said spring, said releasing means forming a means for preventing the rotation of one part on another.

ln testimony whereof I hereunto set my hand this 26th day of January, 1908.
